The results indicate that germination of the second taro happened from 46 d after sprouting （7-8 leaves）; the first taro began to expand, from 125 d after sprouting （12 leaves） when the the second taro was been formed; the third taro began to form from 141 to 150 d after sprouting （15-16 leaves）. The fresh weight of the second and third taros quickly increased from the time of 15 leaves to harvest. Early September is a transformation term of Xiangsha taro from vegetative body dominant to corm growth dominant.展开更多

The best substrate for propagation was assessed： （0） wetland; （1） sand/wetland; （2） sawdust/wetland; （3） sand/sawdust/wetland. Young shoots＇ growth was observed in situ for 8 weeks. A significant difference （P 〈 0.05） was observed in the appearance of young shoots and leaves in nursery. The highest average number of young shoots and leaves （0.62 ± 0.09） was found in substrates 0 and 1, the lowest （0.31 ± 0.08） in substrate 3. Substrate 3 showed the lowest number of young leaves （0.41 ± 0.16） and substrate 2 the highest （0.97 ±0.24）. A significant difference in the mortality rate of cuttings （P 〈 0.05） was observed： 68.75% and 53.12% in substrates 2 and 3, respectively. On farm, new leaves and young shoots＇ appearance showed a highly significant difference. Plants growing in substrates 2 and 3 showed the highest number of leaves. New shoots developed only in plants growing in substrates 0 and 1. These results suggest that it is possible to domesticate H. azurea for leaves＇ production in quantity and quality, and open up better opportunities for its cultivation.展开更多
